Ama-Circuit Breaker wekesi elibunjiwe
A i-molded case circuit breaker (MCCB)wuhlobo lwe-circuit breaker olusetshenziswa kabanzi ukuvikela ugesi ezikhungweni zezimboni nezohwebo ngenxa yekhono layo lokuhlinzeka ngokuvikeleka okuthembekile nokuphephile ngokumelene ne-overcurrent, i-short circuits namanye amaphutha kagesi.Kulesi sihloko, sizobheka ngokujulileAma-MCCBsfuthi baxoxe ngezici zabo, izimiso zokusebenza, ukwakhiwa, kanye nezicelo.
Izici ze-MCCBs
Ama-MCCB aklanywe ngemisebenzi eminingana esiza ukuvikela amasistimu kagesi ngendlela ephephile nethembekile.Ezinye izici ezibalulekile ze-MCCB zifaka:
- Umthamo omkhulu wokuphuka:Ama-circuit breakers abunjiweziyakwazi ukuphula imisinga efinyelela ezinkulungwaneni zama-ampere, okuwenza alungele ukusetshenziswa kwamandla aphezulu.
- Indlela yohambo lwe-Thermal-magnetic:Ama-circuit breakers abunjiwesebenzisa indlela yohambo lwe-thermal-magnetic ukuze uthole futhi uphendule kumasekhethi adlulele kanye namafushane.Ama-elementi ohambo olushisayo aphendula ekulayisheni ngokweqile, kuyilapho ama-elementi ohambo kazibuthe aphendula kumasekhethi amafushane.
- Isilungiselelo Sohambo Esilungisekayo: Ama-MCCB anezilungiselelo zohambo ezilungisekayo, eziwavumela ukuthi asethelwe ezingeni elifanele lohlelo olufunekayo.
- Uhlu olubanzi lwamasayizi ozimele: Ama-MCCB atholakala ngamasayizi ahlukahlukene ozimele, avumela ukuthi asetshenziswe ezinhlotsheni ezihlukahlukene. .I-elementi yohambo olushisayo izwa ukushisa okukhiqizwa ukugeleza kwamandla kumjikelezo futhi igingqa isinqamuli sesekethe lapho i-current idlula isilinganiso sohambo.Isici sohambo lukazibuthe sizwa inkambu kazibuthe ekhiqizwe isekethe emfushane, ikhubekisa isinqamuli sesekethi cishe ngokushesha.Isakhiwo sekhesi elibunjiwe
- I-MCCB iqukethe izindlu zepulasitiki ezibunjiwe ezihlala indlela yohambo, abathintwayo kanye nezingxenye ezithwalayo zamanje.
- Othintwayo benziwe ngezinto ezisebenza kakhulu njengethusi, kuyilapho indlela yohambo iqukethe umucu we-bimetallic kanye nekhoyili kazibuthe.
Ukusetshenziswa kwe-MCCB
Ama-MCCB avame ukusetshenziswa ezinhlelweni ezahlukahlukene ezifana nalezi:
- Uhlelo lokusabalalisa amandla
- Isikhungo Sokulawula Izimoto
- Imishini yezimboni
- Ama-Transformers
- Isethi ye-generator
Ekuphetheni
Ama-circuit breaker abunjiwe angamadivayisi athembekile futhi asebenza ngempumelelo okuvikela ugesi.Ukwakhiwa kanye nezici zabo kuzenza zilungele ukusetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza ezifana nama-transformer, amasistimu okusabalalisa amandla, nezikhungo zokulawula izimoto.Indlela yabo yohambo lwe-thermal-magnetic, umthamo omkhulu wokuphuka kanye nezilungiselelo zohambo ezilungisekayo zibenza babe ukukhetha okudumile ekuvikelweni kukagesi ezikhungweni zezentengiselwano nezimboni.
